My 10 month old baby has recently developed light white discoloration on her cheeks. what cud be the reason. showed it to doctor he prescribed mometasol but isnt helping much

mum, these patches are actually common, and often appear after exposure to the sun. it can actually also be a very mild form of eczema, so if your baby has dry skin, it will be more prominent. check with your doctor as you mentioned the medication is not helping, you can also visit a pediatric skin specialist for the same.
